Medicare Mapper

We decoded the 2011 Hospital Services Area File, tied it to geographic data and put it on a map. With Medicare Mapper, you have a simple interface with some intuitive tools to visualize the data that has been locked up in text files, spreadsheets, and if you're lucky, a static map.

We did this so you wouldn't have to.

Obviously, an app like this uses some data. Lots of it. We'd like to acknowledge our contributors:

Medicare Mapper

Medicare Mapper incorporates the national Hospital Service Area data file provided by CMS to show where Medicare services were provided and consumed in 2011.

As a consumer of services, you can see where people went for services. As a provider of services, you can see which ZIP code your patients came from, and the relative amounts of services they received.

The iPad App

... or where residents choose to seek medical care ...

... and more
